h I To all whom it may concern:

Be it known that I, WILLIAM 'Bn's'ir, a citizen of the United States, residing at De- .troit, in the county of Wayne and State of Michigan have invented a new and useful Hydrocar on-Burner, of which the follow ing is a specification.

This invention relates to means for burn- 7 mg gasolene, kerosene, alcohol and other liquid hydro-carbons that can be readily V vaporized, and its object 'is to provide a burner which will produce an intense fire-in minimum time, which shall be simple in.

construction, and which may be easily and I claims.

In the drawing, Figure 1 is an elevation -of this improved burner, parts being broken away to disclose the interior construction Fig. 2 is a central vertical section. Fig. 3

is a plan of a spacing plate.

Similar reference characters refer to like parts throughout the several views.

The burner is made up of an inner cylin"- drical chimney 1 having holes 2 to permit air to pass throughto the flame between it and the outer chimney 3, also perforated to permit the passage of air. 'A central imperforate tube 4 extends down from the im-,

perforate top 5, and may be provided with. a pair of circumferential ribs 6- tohold the circular plate 7 in position, which platepositions. the tube 4. The inner chimney may also have two circumferential ribs 8 to hold the ring 9 in position, which ring is provided with inwardly extending arms 10 to position the tube 4, but which permit the free flow of air. See Fig. 3.

Integral with the mner chimney 1 is a trough having sides 12 and 13 and bottom 14, in which trough rests the asbestos ring 15. Aledge 16 is integral with the side 13 and is in turn formed with a cylindrical flange. 17. The outer chimney 3 preferably Specification of Letters Patent.

outer chimney is preferably formed with two circumferential ribs 18 which receive the inner edge of a circumferential baffleplate between them, the plate consisting of a radial ring 319, conical portion 20 and cylinder 21.

Fuel is'supplied to this burner by a connection 23, nipple 24, valve body 25, pipe 26 and elbow 27. In the .valve body 25 is mounted a needle-valve 28 having a handwheel 29. 'Any other desired fuel control may be employed. Connected to the elbow 27 is a ring 30 that extends over the cylin-' dricalflange'17 onthe ledge 16 and outside .'pass into the space between the chimneys through the holes in the outer chimney. It is deslrablethat a lip .34 'or'other guide be formed on or connected to the 'elbow 27 and -contactwith the ledge 16 in order that the fuel will flow down at a'c'onstant' rate and not in drops. Surroundin the burner is a frusto conioal shield. 36 wh1ch prevents cur rents of' air from affecting the flame, said Patented Mar. 28, 1916. Application filed January 6, 1915; Serial No. 771.

fits quite tightly within the wall 13, The

shield having small legs 37 and 38 on its inner surface to engage the bafile-ring 20 ,and'thus position theshield. To igmte the burner, the valve is opened so that a small amount of fuel can flow into j the trough and saturate, the asbestos ring 15. A flame is then applied to the ring which causes the fuel to ignite and the inner chimney 1 to be heated very quickly and with it the fuel trough. By forming the trough and innerchimney of the same piece of metal, or of two pieces soldered or welded together so as to be integralineflect, the heat applied to the inner chimney will be transmitted almost instantly to the fuel trough, resulting-in the fnel being quickly evaporated and ignited. The outen-chimney also transmits its heatto the trough because it fits within the flange 13.

When the ledge 16 is integral with. the

trough, the fuel as it 27 is heated at once. It flows through the flows from the elbow;

neys, air passing to the flame through the 'holes in the chimneys l and 3. If the fuel is fed insuflicient quantities to cause the flame to extend above the top 5, air will pass to the inside of this flame from the pipe 4. By reason of the peculiar constructionof this burner a full fire can be obtained in about one third of the time required by burners of the usual construction. The flame can be absolutely controlled by the valve 28, because the trough is at such a high temperature that there is'no accumulation of the heavier-portions of thefuel, all of the fuel being consumed as it is fed to the burner.

The proportions and details of the'construction can all be modified by those skilled in the art without departing from the spirit of my invention as set forth ,in the claims.

I claim 1. In a hydro-carbon burner, the combination of. a cylindrical perforated inner chimney and a fuel trough integral therewith, said trough having a cylindrical flange on its outer edge, a top for the inner chimney, an outer cylindrical chimney extend-- ing down within the flange, an annularledge on the trough, a cover for the ledge, means for delivering liquid fuel onto the. ledge, and an outer shield forisaidburner.

2. In a hydro-carbon burner, the combi-' nation of cylindrical perforated outer and inner chimneys, a trough connecting to the inner chimney and having a flange extending up in engagement with the outer chimney and having an outwardly extending ledge at its upper edge, and a pipe for delivering liquid .fuel to the ledge in such a manner as to prevent the forming of drops of fuel at the discharge end of the pipe.

3. In a hydro-carbon burner, the combination of two perforated chimneys and a fuel trough extending from the lower end of the inner chimney to the lower end of the outer chimney and having an outer flange extending up around the lower end of the outer chimney, a ledge extending around the outer chimney above said flange and having an upturned outer edge, a cover for the ledge, and a liquid fuel conveyer mounted adjacent the ledge to discharge the fuel thereon in such a'manner as to prevent the forming of drops of fuel at the discharge end of said conveyer.

4. In a hydro-carbon burner, the combination of a perforated inner chimney and a fuel trough connected thereto, an outer perforated chimney mounted in said trough,

.a ledge integral with the trough extending around the outer chimney, a cover for the trough. means connected to said trough to feed liquid fuel thereto for said burner, and

nation of a cylindrical perforated inner 30 I chimney and a fuel trough integral there- V with, an outer perforated chimney mounted in said trough, a ledge integral with the trough extending around the outer chim; ney, a cover for the ledge, means connected to said cover and contacting with the ledge to feed liquid fuel onto the ledge for said burner, and means for causing fuel vapor which may escape from the trough to pass inwardly through perforations in the outer chimney..

7. In a hydro-carbon burner, the combination of a cylindrical inner chimney and a fuel trdugh connected thereto, an outer chimney mounted in said trough, a ledge integral with the trough extending around the outer chimney, and a conveyer to guide liquid fuel to the ledge in such a manner as to prevent the forming of drops at the end of the conveyer.

8. In a hydro-carbon burner, the combination of two concentric perforated cylindrical chimneys and a fuel trough integral with one of them into which the other chimney fits tightly, means to feed liquid fuel the tube and having passages for air.
